Hypothesis

How does the MALT1 protein oligomerize to activate the NF-κB signaling pathway?

Conclusion

The study reveals that MALT1 can form oligomers, which may play a crucial role in its function in the immune response.

Supporting Evidence

  • MALT1 plays an important role in the adaptive immune program.
  • The tandem Ig-like domains of MALT1 exist as a mixture of dimer and tetramer in solution.
  • High-resolution structures reveal a protein-protein interface that stabilizes MALT1 oligomerization.

Takeaway

MALT1 is a protein that helps our immune system work, and it can stick together in groups to do its job better.

Methodology

The study used structural biology techniques, including crystallization and size-exclusion chromatography, to analyze the MALT1 protein.
